EX'GAVATING AND HOISTING BUCKET.

SPECIFICATION forming part of Letters Patent No. 528,579, dated November6, 1894.

Application filed December 11, 1893. Serial No.493,374. (No model.)

To @ZZ whom it may concern:

Be it known that I, GURDoN H. WILLIAMS, of Brighton, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Excavating and Hoisting Buckets; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to improvements in excavating and hoisting-buckets,and it consists in certain features of construction, and in combinationsof parts hereinafterdescribed and pointed out in the claims.

In the accompanying drawings,Figure lis a side elevation, mostly'in-central vertical section, of a bucket embodying my invention. Fig. 2 isa top plan of the same, portions being broken away and iu section tomore clearly show the construction. Fig. 3 is an enlarged side elevationin central vertical section on line 3--3, Fig. 2.

My invention pertains more especially to that variety of buckets thatare composed of two or more sections that form the sides and bottom ofthe bucket with the sections pivotally supportedand arranged in such amanner that the sections, in hoisting and lowering the bucket and inconveying thesame from place to place, will be held closed together, andare capable of being swung outwardly upon. their pivotal bearing toseparate them and thereby open the bucket.

My present invention consists more especially in the means employed foroperatively4 connecting the pivotal sections of the bucket with thehoisting-rope in such a manner that the construction is lrenderedassimple and durable as possible without liability of the bucket beingopened during the hoisting and when closed together, as shown in Figs. land 2, form the sides and bottom of the bucketpropel'. Each section A,in the case illustrated, is provided, at its upper and central as, andan inwardly-extending and centrallylocated arm, 0,4, the former, at itsouter eX- tremity,l being operatively connected, by means of a link, B,with the lower portion of a tubular member C, that is located at the topand centrally of the bucket, and has attached, at its upper extremity,the hoistingrope or cable D, and arm a, at its inner eX- tremity, ispivotally connected to a sleeve, E, that easily'embraces member O, saidsleeve being enlarged diametrically at itslower end, as at E', and armsa4 of plates a of the bucketsections being pivoted to one or more lugsor ears projecting laterally and outwardly from the lower extremity of'said enlarged portion of sleeve E. Links B are connected with member Cbelow the upper extremity of the enlarged portion E ofisleeve E, thesame being pivoted preferably, as shown, to one or morelaterally-projecting lugs or ears on member O, and the enlarged portionof sleeve E being slotted, as at E2, toaccommodate the locationl andoperation ot' said links. Plates a, preferably at or near the innerextremities of arms a4, are' operatively connected, respectively, bymeans of one or more links G, with a sleeve, H, easily embracing sleeveE, a pair of links G being preferably employed for each bucket-sectionand said links being preferably pivoted to a laterally-projecting lug orear at or near the upper end of sleeve H. Sleeve H, lat its upperextremity, is also provided with a laterally-projecting lug or ear hthat has attached an upwardly-extending rope or cable I. l v

I would here remark that both ropes or cables D and I are connected withwindingdrums (not shown) and lead from their con- IOO- alreadyindicated, with the lower extremity of sleeves Eand operativelyconnected by means of links B with the hoisting-cable engaging member Cand carry the sections that form the bucket-proper.

The arrangement of parts is such that upon releasing the hoisting ropeor cable or permitting the same to be paid out and placing a draft uponrope or cable I, member C, links zo B, levers a., d3, a4, and attachedbucket-sections shall be actuated in the direction to effect theseparation of the bucket-sections, thereby opening the bucket or placingthe same in condition to take up or discharge its load, as shown indotted lines Fig. 1, and that by releasing or permitting rope or cable Ito pay out, and. causing the draft to be on the hoisting-rope or cable,the parts of the bucket just referred to will assume the position shownin solid lines in the drawings, as required preparatory to the hoistingand conveyance of the load, the upper end of the enlarged portion E ofmember E` forming a stop to limit the elevation of thehoisting-ropeengaging-member independently of the other parts of thebucket.

I would also remark that sleeve H, at its lower end, has attached one ormore ropes, chains or cables K (see Fig. 3) that lead thence downwardlyto and over sheaves K suitably supported within the enlarged portion Eof sleeve E and thence upwardly a suitable distance into member C, towhich the chains or cables K are connected, as at K2, member C and theenlarged portion E of sleeve E, being slotted, as at C and E3,respectively, to accommodate the location and operation of said chainsor cables.

By the construction thus described, it Will be observed that chains orcables K assist in the operations of opening and closing the bucket.

l. In a bucket of the variety indicated, the 45 combination with thesections that form the sides and bottom of the bucket-proper, of areciprocating hoisting-cable-engaging-member located at the top andcentrally of the bucket, a sleeve or tubular member E embracing vsaidhoisting-cable engaging-member, levers rigid with the aforesaidbucketsections and pivotally connected to the lower end of the aforesaidsleeve,links operatively connecting said levers with the hoisting-ca- 55ble engaging-member, and suitable means operatively connected with thebucket-sec` tions for actuating the latter to separate or open,substantially as set forth.

2. In a bucket of the variety indicated, the

5o combination with the sections thatform the sides and bottom of thebucketproper,of a reciprocating hoisting-cableengagingmern ber locatedat the top and centrally of the bucket, a sleeve or tubular member Eembracing said hoisting-cable-engaging-member, said sleeve beingenlarged diametrically at its lower end, a plate a secured to each ofthe aforesaid bucket-sections, said plates having, respectively, anupwardly-extending arm as and an inwardly-extending arm a4, the lat- 7oter being pivotally connected to the lower end of the aforesaid sleeve,links operatively connecting arms a3 of said plates with thehoisting-cable-engagingmember, and suitable means operatively connectedwith said plates at or near the inner extremity of theinwardly-extending arms of the plates for actuating the aforesaidbucket-sections to separate or open, and the aforesaid sleeve beingslotted to accommodate the location and op- 8o eration of the aforesaidlinks, substantially as set forth.

3. In abucket of the variety indicated, the combination of the sectionsthat form the sides and bottom of the bucket-proper, said sections beingadapted to separate and thereby open ther bucket; a relativelystationary member E; levers, a a3 a4,fnlcrumed to said stationarymember, 'and rigidly secured 4to the aforesaid bucket-sections; areciprocating hoistingcable-engaging-member and links B operativelyconnecting the `aforesaid levers with said hoisting-cable-engaging-member; another reciprocating member H and means operatively connecting thesame with the bucket-sections; a rope or cable attached to said member Hfor elevating the latter, and one or more chains or cables attached atopposite ends to the aforesaid two reciprocating-members, respectively,the arrangement roo of parts being substantially as and for the purposeset forth.

4. In a bucket of the varietyindicated, the combination of the sectionsthat form the sides and bottomof the bucket-proper; memx05 ber Eenlarged at its lower end, as at E', and slotted, as at E2, E3;hoisting-cable; inner reciprocatingmember C having laterally-projectinglugs C; levers a a3 a4; links B; outer reciprocating-sleeve, I-I; cableI; links G; one 11o or more chains or cables K, and sheaves or guidesK', all arranged and operating substantially as shown, for the purposespecified.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 18th day of November, 1893.

GURDON H. WILLIAMS.
